Solr Mongo/DocDB Delta Import Query is not working - mongodb

Question

I am trying to import data from Document DB to solr-5.4.1.
Full import is executing properly but delta import is not working. When I execute delta import nothing happens
Here is the current delta configuration
deltaQuery="{'lastUpdatedDate':{$exists:true},'lastUpdatedDate':{$gt: Date('${dih.last_index_time}')}}"
deltaImportQuery="{'_id':'${dih.delta._id}'}">
whole db-data-config.xml
<dataConfig>
<propertyWriter dateFormat="yyyy-MM-dd'T'HH:mm:ss.SSSXXX" type="SimplePropertiesWriter" filename="dataimport.properties"/>
<document name="tvTitleSearch">
<entity name="tvTitleSearch"
processor="MongoEntityProcessor"
query=""
collection="tvTitleSearch"
datasource="MyMongo"
transformer="MongoMapperTransformer"
deltaQuery="{'lastUpdatedDate':{$exists:true},'lastUpdatedDate':{$gt: Date('${dih.last_index_time}')}}"
deltaImportQuery="{'_id':'${dih.delta._id}'}">
<field name="id" column="_id" indexed="true" type="uuid" stored="true" mongoField="_id"/>
<field column="lastUpdatedDate" sourceColName="lastUpdatedDate" dateTimeFormat="yyyy-MM-dd'T'HH:mm:ss.SSSXXX" locale="en"/>
</entity>
</document>
</dataConfig>
sample from managed-schema file
<field type="date" name="modifiedDate" indexed="true" stored="true"/>
<field type="date" name="lastUpdatedDate" indexed="true" stored="true"/>
the value stored in DocumentDB:
lastUpdatedDate:2019-11-24T11:43:46.045+00:00
I tried to follow the date-time format as stored in DocumentDB, but still, it did not work, also, I tried suggestions from other similar question asked here but no luck. I tried below snippet in delta query
{lastUpdatedDate : {$gt: ISODate('${dih.last_index_time}')}} , but I got JSON Prasing Excpetion
but got below Exception
java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: com.mongodb.util.JSONParseException:
{'lastUpdatedDate':{$exists:true},'lastUpdatedDate':{$gt: ISODate('2019-11-20T13:14:30.576-08:00')}}
I tried following configuration too
deltaQuery="{'lastUpdatedDate':{$exists:true},'lastUpdatedDate':{$gt:
{$date:'${dih.last_index_time}'}}}"
could someone please help me or provide any suggestions to trigger delta query

Answer 1

The correct way to use the deltaQuery is
deltaQuery="{'lastUpdatedDate':{$exists:true},'lastUpdatedDate':{$gt: {$date:'2020-03-13T08:44:06.959Z'}}}"
as you can see here
However, the SOLR will use ${dih.last_index_time} that is by default formated as 2020-03-13 08:44:06. You'll need to change the format by adding something like the following setting inside your <dateConfig> element.
<propertyWriter dateFormat="yyyy-MM-dd'T'HH:mm:ss.SSSXXX" type="SimplePropertiesWriter" filename="my_dih.properties" locale="en-US" />
